It's a roto-zip style glass bit. Not the one that looks like an arrowhead; I tried that and it SUCKED. This one looks more like it's got tiny barbs down the shaft about 2 cm.

You have to drill under water or the glass will overheat and crack, and you'll dull the bit before you even finish one project.
